データ処理装置、物理量計測装置、データ処理システム、及び、データ処理方法Data processing device, physical quantity measuring device, data processing system, and data processing method
　本発明は、データ処理装置、物理量計測装置、データ処理システム、及び、データ処理方法に関する。
　本願は、２０２２年９月２１日に日本に出願された特願２０２２－１５０４２４号について優先権を主張し、その内容をここに援用する。 The present invention relates to a data processing device, a physical quantity measuring device, a data processing system, and a data processing method.
This application claims priority to Japanese Patent Application No. 2022-150424 filed in Japan on September 21, 2022, the contents of which are incorporated herein.
　従来、監視対象物に計測装置を取り付けて、監視対象装置の状態を監視することが行われている。例えば、特許文献１には、監視対象物の振動等を測定する測定センサと、測定センサによる測定を所定の測位サイクルで行う測定制御手段と、測定センサによる測定データを診断装置に送信する通信処理手段とを備える通信機能付き測定器が開示されている。 Conventionally, a measuring device is attached to a monitored object to monitor the state of the monitored device. For example, Patent Document 1 describes a measurement sensor that measures vibrations, etc. of a monitored object, a measurement control unit that performs measurements by the measurement sensor in a predetermined positioning cycle, and a communication process that transmits measurement data by the measurement sensor to a diagnostic device. A measuring instrument with a communication function is disclosed.
日本国特開２０１４－２２５０８０号公報Japanese Patent Application Publication No. 2014-225080
　特許文献１に開示された通信機能付き測定器では、測定制御手段が、常時はスリープ状態にあり、測定サイクルにより設定された時点に至ると、自動起動して測定用センサに計測させて、その測定データを通信処理手段により送信させる。 In the measuring device with a communication function disclosed in Patent Document 1, the measurement control means is always in a sleep state, and when a set point in the measurement cycle is reached, it automatically starts up and causes the measurement sensor to perform the measurement. The measurement data is transmitted by the communication processing means.
　ここで、特定時点の測定データでは、測定センサの測定環境や監視対象物の運転状況等の影響を受けて突発値が含まれる可能性があるため、複数時点の測定データに対して移動平均等の演算を行うことが有効である。また、監視対象物の状態（異常や故障等）を判定する際に、その判定する状態に応じて、例えば、測定サイクルを時間単位や日単位で設定するような傾向監視（第１の監視処理）と、測定サイクルを秒単位や分単位で設定するようなリアルタイム監視（第２の監視処理）とを使い分けたり、併用したりすることが必要である。しかしながら、特許文献１に開示された通信機能付き測定器では、複数時点の測定データに対して移動平均等の演算を行うことや、複数の測定サイクルで監視するようなことは開示されていない。 Here, the measurement data at a specific point in time may include sudden values due to the influence of the measurement environment of the measurement sensor, the driving condition of the monitored object, etc., so moving averages etc. It is effective to perform the following calculations. In addition, when determining the state of the monitored object (abnormality, failure, etc.), depending on the state to be determined, for example, trend monitoring (first monitoring process ) and real-time monitoring (second monitoring processing) in which the measurement cycle is set in seconds or minutes, or in combination. However, the measuring device with a communication function disclosed in Patent Document 1 does not disclose that calculations such as a moving average are performed on measurement data at a plurality of points in time, or that monitoring is performed in a plurality of measurement cycles.
　本発明は、上述した課題に鑑み、監視周期が異なる第１の監視処理及び第２の監視処理を実現しつつ、消費電力の低減を可能とするデータ処理装置、物理量計測装置、データ処理システム、及び、データ処理方法を提供することを目的とする。 In view of the above-mentioned problems, the present invention provides a data processing device, a physical quantity measuring device, a data processing system, and a physical quantity measuring device that can reduce power consumption while realizing a first monitoring process and a second monitoring process with different monitoring cycles. and to provide a data processing method.
　上記目的を達成するために、本発明の一態様に係るデータ処理装置は、計測対象の物理量を物理量データとして繰り返し取得し、取得した前記物理量データに対して所定の演算を行うことにより処理データを生成する演算処理部と、
　前記演算処理部により前記処理データが生成される毎に前記処理データをデータ収集装置に順次送信する通信処理部と、を備え、前記演算処理部は、所定の開始条件が満たされたとき、前記物理量データを所定のデータ点数だけ繰り返し取得し、取得した前記データ点数分の前記物理量データに対して前記演算を行うことにより第１の前記処理データを生成する第１の演算処理を実行し、前記第１の演算処理の実行後に所定の終了条件が満たされていないとき、所定の待機時間だけ待機状態に移行し、前記待機時間の経過後に最新時点の前記物理量データを取得し、取得した前記最新時点の前記物理量データと、前記最新時点よりも過去に取得した過去時点の前記物理量データとからなる前記データ点数分の前記物理量データに対して前記演算を行うことにより第２の前記処理データを生成する第２の演算処理を、前記終了条件が満たされるまで繰り返し実行する。 In order to achieve the above object, a data processing device according to one aspect of the present invention repeatedly acquires a physical quantity to be measured as physical quantity data, and performs a predetermined operation on the acquired physical quantity data to obtain processed data. An arithmetic processing unit that generates
a communication processing unit that sequentially transmits the processed data to a data collection device each time the processing data is generated by the calculation processing unit, and the calculation processing unit transmits the processing data when a predetermined start condition is satisfied. Repeatedly acquiring physical quantity data for a predetermined number of data points, and performing the first calculation process to generate the first processed data by performing the calculation on the physical quantity data corresponding to the acquired number of data points, When a predetermined end condition is not satisfied after the first calculation process is executed, the system enters a standby state for a predetermined standby time, acquires the physical quantity data at the latest point in time after the elapse of the standby time, and acquires the latest acquired physical quantity data. Generating the second processed data by performing the calculation on the physical quantity data for the number of data points, which is made up of the physical quantity data at a point in time and the physical quantity data at a past point in time acquired in the past than the latest point in time. The second arithmetic processing is repeatedly executed until the termination condition is satisfied.
　本発明に係るデータ処理装置によれば、所定の開始条件が満たされると、演算処理部が、データ点数分の物理量データに対して演算を行うことにより第１の処理データを生成する第１の演算処理を実行し、通信処理部によりその第１の処理データを送信する。このとき、所定の終了条件が満たされることで、第２の演算処理は実行されない。これにより、１回分の処理データだけが送信されるので、例えば、傾向監視（第１の監視処理）に利用することができる。また、第１の監視処理では、待機時間による待機状態に移行しないため、待機時間分の消費電力の低減が図られる。一方、第１の演算処理の実行後に所定の終了条件が満たされていないと、演算処理部が、所定の待機時間だけ待機状態に移行し、最新時点の物理量データを含むデータ点数分の物理量データに対して演算を行うことにより第２の処理データを生成する第２の演算処理を、終了条件が満たされるまで繰り返し実行し、通信処理部によりその第２の処理データを順次送信する。これにより、処理データが繰り返し送信されるので、例えば、リアルタイム監視（第２の監視処理）に利用することができる。その際、通常の動作状態よりも消費電力が少ない待機状態に待機時間だけ移行し、待機時間の経過に合わせて物理量データが取得されて演算が行われるので、無用な物理量データの取得や演算が回避されることによる消費電力の低減と、待機状態への移行による消費電力の低減とが図られる。したがって、監視周期が異なる第１の監視処理及び第２の監視処理を実現しつつ、消費電力の低減を図ることができる。 According to the data processing device according to the present invention, when the predetermined start condition is satisfied, the arithmetic processing unit generates the first processed data by performing a calculation on the physical quantity data corresponding to the number of data points. The arithmetic processing is executed and the first processed data is transmitted by the communication processing section. At this time, the second arithmetic processing is not executed because a predetermined termination condition is satisfied. As a result, only one batch of processing data is transmitted, so that it can be used, for example, for trend monitoring (first monitoring processing). Furthermore, in the first monitoring process, since the device does not enter a standby state due to the standby time, power consumption can be reduced by the amount of the standby time. On the other hand, if the predetermined termination condition is not met after the first calculation process is executed, the calculation processing section shifts to a standby state for a predetermined waiting time, and the physical quantity data corresponding to the number of data points including the physical quantity data at the latest point in time is stored. A second arithmetic process of generating second process data by performing a calculation on the second process data is repeatedly executed until an end condition is satisfied, and the communication processing unit sequentially transmits the second process data. Since the processed data is thereby repeatedly transmitted, it can be used, for example, for real-time monitoring (second monitoring processing). At that time, the system shifts to a standby state that consumes less power than the normal operating state for the duration of the standby time, and as the standby time passes, physical quantity data is acquired and calculations are performed, so unnecessary physical quantity data acquisition and calculations are avoided. By avoiding this, power consumption is reduced, and by transitioning to a standby state, power consumption is reduced. Therefore, it is possible to reduce power consumption while realizing the first monitoring process and the second monitoring process with different monitoring cycles.

　図２は、物理量計測装置３の一例を示すブロック図である。物理量計測装置３は、その主要な構成要素として、上記の物理量センサ３０の他に、データ処理装置３１を構成する制御部３２、通信部３３、記憶部３４及び電源３５を備える。 FIG. 2 is a block diagram showing an example of the physical quantity measuring device 3. The physical quantity measuring device 3 includes, as its main components, a control section 32, a communication section 33, a storage section 34, and a power supply 35, which constitute a data processing device 31, in addition to the physical quantity sensor 30 described above.
　制御部３２は、例えば、記憶部３４に記憶されたデータ処理プログラム３４０を実行することにより、演算処理部３２０、及び、通信処理部３２１として機能する。通信部３３は、ネットワーク７を介して、例えば、データ収集装置４との間で各種のデータを送受信する通信インターフェースとして機能する。記憶部３４は、物理量計測装置３の動作で使用される各種のプログラム（データ処理プログラム３４０等）やデータ（設定情報３４１等）を記憶する。設定情報３４１には、例えば、物理量計測装置３が動作する際に制御部３２により参照される設定パラメータ（データ点数Ｄｎ、待機時間Ｗｔ等）が記憶されるとともに、例えば、データ収集装置４を介して設定可能に構成される。電源３５は、例えば、一次電池、二次電池、太陽電池、燃料電池等で構成され、物理量計測装置３の各部に電力を供給する。なお、電源３５は、ポンプ装置２から電力供給を受けてもよい。 The control unit 32 functions as an arithmetic processing unit 320 and a communication processing unit 321, for example, by executing a data processing program 340 stored in the storage unit 34. The communication unit 33 functions as a communication interface that transmits and receives various data to and from the data collection device 4 via the network 7, for example. The storage unit 34 stores various programs (data processing program 340, etc.) and data (setting information 341, etc.) used in the operation of the physical quantity measuring device 3. The setting information 341 stores, for example, setting parameters (number of data points Dn, standby time Wt, etc.) that are referenced by the control unit 32 when the physical quantity measuring device 3 operates, and also stores, for example, setting parameters that are referenced by the control unit 32 when the physical quantity measuring device 3 operates. It is configured to be configurable. The power source 35 is composed of, for example, a primary battery, a secondary battery, a solar cell, a fuel cell, etc., and supplies power to each part of the physical quantity measuring device 3. Note that the power source 35 may receive power supply from the pump device 2.
　演算処理部３２０は、物理量センサ３０により計測された計測対象の物理量を物理量データＤとして繰り返し取得し、その取得した物理量データＤに対して所定の演算を行うことにより処理データＲｐを生成する。物理量データＤに対する演算は、例えば、計測時点が異なる所定のデータ点数分の物理量データＤに対して移動平均を求める。移動平均としては、例えば、単純移動平均や加重移動平均等である。 The arithmetic processing unit 320 repeatedly acquires the physical quantity to be measured measured by the physical quantity sensor 30 as the physical quantity data D, and generates the processed data Rp by performing a predetermined operation on the acquired physical quantity data D. In the calculation for the physical quantity data D, for example, a moving average is calculated for the physical quantity data D for a predetermined number of data points at different measurement points. Examples of the moving average include a simple moving average and a weighted moving average.
　演算処理部３２０は、所定の開始条件が満たされたとき、物理量データＤを所定のデータ点数Ｄｎだけ繰り返し取得し、その取得したデータ点数分の物理量データＤ１に対して演算を行うことにより第１の処理データＲｐ１を生成する第１の演算処理を実行する。第１の監視処理では、後述する第２の演算処理のように、待機時間による待機状態に移行しないため、データ点数分の物理量データＤが取得されて演算が行われるので、待機時間分の消費電力の低減が図られる。 When a predetermined start condition is met, the arithmetic processing unit 320 repeatedly obtains the physical quantity data D by a predetermined number of data points Dn, and performs a calculation on the physical quantity data D1 corresponding to the obtained number of data points. A first arithmetic process is executed to generate processed data Rp1. In the first monitoring process, unlike the second arithmetic processing described later, the physical quantity data D corresponding to the number of data points is acquired and the calculation is performed, so that the physical quantity data D corresponding to the number of data points is acquired and the calculation is performed. Power consumption is reduced.
　また、演算処理部３２０は、第１の演算処理の実行後に所定の終了条件が満たされていないとき、所定の待機時間Ｗｔだけ待機状態に移行し、待機時間Ｗｔの経過後に最新時点の物理量データＤｎｅｗを取得し、その取得した最新時点の物理量データＤｎｅｗと、最新時点よりも過去に取得した過去時点の物理量データＤｐａｓｓとからなるデータ点数分の物理量データＤ２に対して演算を行うことにより第２の処理データＲｐ２を生成する第２の演算処理を、終了条件が満たされるまで繰り返し実行する。 Further, when the predetermined end condition is not satisfied after execution of the first arithmetic processing, the arithmetic processing unit 320 shifts to a standby state for a predetermined standby time Wt, and after the elapse of the standby time Wt, the physical quantity data at the latest point in time is Dnew is acquired, and the second calculation is performed on the physical quantity data D2 for the number of data points consisting of the acquired physical quantity data Dnew at the latest point in time and the physical quantity data Dpass at the past point in time acquired in the past than the latest point in time. The second arithmetic processing for generating the processed data Rp2 is repeatedly executed until the termination condition is satisfied.
　待機時間Ｗｔは、例えば、後述する第２の監視周期Ｓ２から物理量データＤの取得時間と、第２の処理データＲｐ２の演算時間とを減算した時間を目安にして設定される。第２の演算処理では、通常の動作状態よりも消費電力が少ない待機状態に待機時間Ｗｔだけ移行し、待機時間Ｗｔの経過に合わせて物理量データＤが取得されて演算が行われるので、無用な物理量データＤの取得や演算が回避されることによる消費電力の低減と、待機状態への移行による消費電力の低減とが図られる。 The standby time Wt is set, for example, based on the time obtained by subtracting the acquisition time of the physical quantity data D and the calculation time of the second processing data Rp2 from the second monitoring cycle S2 described below. In the second calculation process, the system transitions to a standby state that consumes less power than the normal operating state for only the standby time Wt, and physical quantity data D is acquired and calculations are performed as the standby time Wt elapses, thereby reducing power consumption by avoiding the acquisition and calculation of unnecessary physical quantity data D, and reducing power consumption by transitioning to the standby state.
　データ点数Ｄｎが、例えば、「４点」の場合には、第２の演算処理で演算が行われるデータ点数分の物理量データＤ２は、最新時点の１点の物理量データＤｎｅｗと、最新時点から遡って直近の過去時点である３点分の物理量データＤｐａｓｓ１、Ｄｐａｓｓ２、Ｄｐａｓｓ３とからなる。データ点数分の物理量データＤ２に対する演算として、演算処理部３２０が、例えば、最新時点の物理量データＤｎｅｗを取得する毎に移動平均を求める場合には、過去時点の物理量データＤｐａｓｓ（Ｄｐａｓｓ１、Ｄｐａｓｓ２、Ｄｐａｓｓ３）を記憶部３４に記憶しておき、移動平均を求める際に記憶部３４を参照するようにすればよい。その際、記憶部３４に記憶された物理量データＤｐａｓｓは、記憶部３４の記憶容量等を考慮して、その取得した時点が古い順に削除されるようにすればよい。 For example, when the number of data points Dn is "4 points," the physical quantity data D2 for the number of data points to be calculated in the second calculation process is the physical quantity data Dnew of one point at the latest point, and the physical quantity data Dnew from the latest point. It consists of physical quantity data Dpass1, Dpass2, and Dpass3 for three points, which are the most recent past points. As a calculation for the physical quantity data D2 for the number of data points, for example, when the calculation processing unit 320 calculates a moving average every time it acquires the physical quantity data Dnew at the latest point in time, the calculation processing unit 320 calculates the moving average for the physical quantity data Dpass (Dpass1, Dpass2, Dpass3) at the past point in time. ) may be stored in the storage unit 34, and the storage unit 34 may be referred to when calculating the moving average. At this time, the physical quantity data Dpass stored in the storage unit 34 may be deleted in the order of the oldest acquisition time, taking into consideration the storage capacity of the storage unit 34 and the like.
　開始条件及び終了条件は、例えば、データ収集装置４との通信状態や物理量計測装置３の電源のオンオフ状態に基づいて定められる。例えば、データ収集装置４との通信状態として、演算処理部３２０は、データ収集装置４との通信が開始したとき、開始条件が満たされたと判断し、第１の演算処理を開始し、データ収集装置４との通信が終了したとき、終了条件が満たされたと判断し、第２の演算処理を終了する。また、物理量計測装置３の電源のオンオフ状態として、演算処理部３２０は、物理量計測装置３の電源がオンされたとき、開始条件が満たされたと判断し、第１の演算処理を開始し、物理量計測装置３の電源がオフされたとき、終了条件が満たされた判断し、第２の演算処理を終了する。 The start condition and the end condition are determined based on, for example, the communication state with the data collection device 4 and the on/off state of the power supply of the physical quantity measuring device 3. For example, as for the communication state with the data collection device 4, when the communication with the data collection device 4 starts, the calculation processing unit 320 determines that the start condition is satisfied, starts the first calculation process, and collects the data. When the communication with the device 4 is completed, it is determined that the termination condition is satisfied, and the second arithmetic processing is terminated. Further, as the on/off state of the power of the physical quantity measuring device 3, when the power of the physical quantity measuring device 3 is turned on, the arithmetic processing unit 320 determines that the start condition is satisfied, starts the first arithmetic processing, and When the power of the measuring device 3 is turned off, it is determined that the termination condition is satisfied, and the second arithmetic processing is terminated.
　なお、演算処理部３２０は、終了条件が満たされたとき、第２の演算処理を終了し、待機状態よりも消費電力が少ないスリープ状態に移行し、開始条件が満たされたとき、スリープ状態から復帰し、第１の演算処理を開始するようにしてもよい。 Note that when the end condition is met, the arithmetic processing unit 320 ends the second arithmetic processing and shifts to the sleep state, which consumes less power than the standby state, and when the start condition is met, the arithmetic processing unit 320 exits the sleep state. It is also possible to return and start the first arithmetic processing.
　通信処理部３２１は、演算処理部３２０により処理データＲｐが生成される毎に処理データＲｐをデータ収集装置４に順次送信する。演算処理部３２０が、第１の演算処理にて第１の処理データＲｐ１を生成した場合には、通信処理部３２１は、第１の処理データＲｐ１を送信し、第２の演算処理にて第２の処理データＲｐ２を生成した場合には、通信処理部３２１は、第２の処理データＲｐ２を送信する。 The communication processing unit 321 sequentially transmits the processing data Rp to the data collection device 4 every time the processing data Rp is generated by the arithmetic processing unit 320. When the arithmetic processing unit 320 generates the first processed data Rp1 in the first arithmetic processing, the communication processing unit 321 transmits the first processed data Rp1 and generates the first processed data Rp1 in the second arithmetic processing. When the second processing data Rp2 is generated, the communication processing unit 321 transmits the second processing data Rp2.
　通信処理部３２１により送信された処理データＲｐは、データ収集装置４により受信されると、データ収集装置４によりデータ管理装置５にさらに送信されることで、データベース５０に格納される。また、処理データＲｐは、データ収集装置４の表示画面に表示されてもよい。なお、処理データＲｐには、通信処理部３２１又はデータ収集装置４により、例えば、ポンプ装置２及び物理量計測装置３の少なくとも一方を識別するための識別情報（ポンプ装置２の装置ＩＤ、物理量計測装置３の装置ＩＤ等）が付加されてもよく、その場合には、処理データＲｐ及び識別情報が関連付けられた状態でデータベース５０に格納されるようにしてもよい。 When the processing data Rp transmitted by the communication processing unit 321 is received by the data collection device 4, it is further transmitted from the data collection device 4 to the data management device 5, thereby being stored in the database 50. Further, the processed data Rp may be displayed on the display screen of the data collection device 4. Note that the processing data Rp includes, for example, identification information for identifying at least one of the pump device 2 and the physical quantity measuring device 3 (device ID of the pump device 2, physical quantity measuring device 3) may be added, and in that case, the processing data Rp and the identification information may be stored in the database 50 in an associated state.

The communication unit 41 functions as a communication interface for transmitting and receiving various data between, for example, the physical quantity measuring device 3 and the data management device 5 via the network 7. The storage unit 42 stores various programs (such as the data collection program 420) and data (such as setting information 421) used in the operation of the data collection device 4. The setting information 421 stores, for example, setting parameters (such as the first monitoring period S1 and the second monitoring period S2) referenced by the control unit 40 when the data collection device 4 operates, and is configured to be set, for example, via the data collection device 4. The input unit 43 and the output unit 44 function as a user interface by accepting input operations from the user and outputting various information via a display screen or voice.
　第１の収集処理部４００は、第１の監視周期Ｓ１に基づいて、処理データＲｐ１を収集する第１の監視動作を行う。例えば、第１の収集処理部４００は、第１の監視処理を、第１の監視周期Ｓ１に従って繰り返し実行することにより、処理データＲｐ１を収集する。第１の監視処理は、物理量計測装置３との通信を開始し、物理量計測装置３から第１の処理データを受信し、物理量計測装置３との通信を終了することである。第１の監視周期Ｓ１は、例えば、傾向監視（第１の監視処理）に適した値として、時間単位や日単位で設定される。 The first collection processing unit 400 performs a first monitoring operation to collect processing data Rp1 based on the first monitoring cycle S1. For example, the first collection processing unit 400 collects the processed data Rp1 by repeatedly executing the first monitoring process according to the first monitoring cycle S1. The first monitoring process is to start communication with the physical quantity measuring device 3, receive first processing data from the physical quantity measuring device 3, and end communication with the physical quantity measuring device 3. The first monitoring period S1 is set, for example, in units of hours or days, as a value suitable for trend monitoring (first monitoring processing).
　第２の収集処理部４０１は、第１の監視周期Ｓ１よりも短い第２の監視周期Ｓ２（＜Ｓ１）に基づいて、処理データＲｐ１、Ｒｐ２を収集する第２の監視動作を行う。例えば、第２の収集処理部４０１は、物理量計測装置３との通信を開始し、物理量計測装置３から第１の処理データＲｐ１を受信するとともに、第２の監視処理を実行することにより、処理データＲｐ１、Ｒｐ２を収集する。第２の監視処理は、第２の処理データＲｐ２を第２の監視周期Ｓ２に従って繰り返し受信し、物理量計測装置３との通信を終了することである。第２の監視周期Ｓ２は、例えば、リアルタイム監視（第２の監視処理）に適した値として、秒単位や分単位で設定される。 The second collection processing unit 401 performs a second monitoring operation to collect the processed data Rp1 and Rp2 based on a second monitoring cycle S2 (<S1) that is shorter than the first monitoring cycle S1. For example, the second collection processing unit 401 starts communication with the physical quantity measuring device 3, receives the first processed data Rp1 from the physical quantity measuring device 3, and executes the second monitoring process. Collect data Rp1 and Rp2. The second monitoring process is to repeatedly receive the second processing data Rp2 according to the second monitoring cycle S2, and to terminate communication with the physical quantity measuring device 3. The second monitoring period S2 is set, for example, in seconds or minutes as a value suitable for real-time monitoring (second monitoring processing).

（第１の監視動作）
　以下では、データ収集装置４が、第１の監視動作を開始するように指示する入力操作を受け付けた場合について、図５を参照して説明する。 (First monitoring operation)
Below, a case where the data collection device 4 receives an input operation instructing to start the first monitoring operation will be described with reference to FIG. 5.
　まず、データ収集装置４の第１の収集処理部４００は、上記の入力操作を受け付けると、図５に示すステップＳ１００にて、物理量計測装置３との通信を開始するための通信開始要求を物理量計測装置３に送信する。 First, when the first collection processing unit 400 of the data collection device 4 receives the above input operation, in step S100 shown in FIG. Send to measuring device 3.
　そして、ステップＳ２００にて、物理量計測装置３の演算処理部３２０は、データ収集装置４から通信開始要求を受信すると、データ収集装置４との間で通信を開始し、ステップＳ２１０にて、開始条件が満たされた判断する。その際、制御部３２がスリープ状態である場合には、ステップＳ２１１にて、スリープ状態から復帰する。 Then, in step S200, when the arithmetic processing unit 320 of the physical quantity measuring device 3 receives the communication start request from the data collecting device 4, it starts communication with the data collecting device 4, and in step S210, the processing unit 320 of the physical quantity measuring device 3 Judgment is fulfilled. At this time, if the control unit 32 is in the sleep state, it returns from the sleep state in step S211.
　次に、ステップＳ２２０～Ｓ２２１にて、演算処理部３２０は、第１の演算処理を実行する。具体的には、演算処理部３２０は、ステップＳ２２０にて、物理量データＤを所定のデータ点数Ｄｎ（本実施形態では、Ｄｎ＝「４点」）だけ繰り返し取得する。そして、ステップＳ２２１にて、その取得した４点の物理量データＤ１に対して、例えば、移動平均を求める演算を行うことにより第１の処理データＲｐ１を生成する。 Next, in steps S220 to S221, the calculation processing unit 320 executes a first calculation process. Specifically, in step S220, the calculation processing unit 320 repeatedly acquires physical quantity data D a predetermined number of data points Dn (in this embodiment, Dn = "4 points"). Then, in step S221, the calculation processing unit 320 performs an operation to obtain, for example, a moving average on the acquired four points of physical quantity data D1 to generate first processing data Rp1.
　次に、ステップＳ２３０にて、通信処理部３２１は、ステップＳ２２０～Ｓ２２１（第１の演算処理）で生成した第１の処理データＲｐ１をデータ収集装置４に送信する。 Next, in step S230, the communication processing unit 321 transmits the first processing data Rp1 generated in steps S220 to S221 (first calculation processing) to the data collection device 4.
　そして、ステップＳ１１０にて、第１の収集処理部４００は、データ収集装置４から第１の処理データＲｐ１を受信すると、その第１の処理データＲｐ１を出力する出力処理として、例えば、データ管理装置５のデータベース５０に格納したり、データ収集装置４の表示画面に表示したりする。 Then, in step S110, when the first collection processing unit 400 receives the first processing data Rp1 from the data collection device 4, the first collection processing unit 400 performs output processing to output the first processing data Rp1, for example, to the data management device. 5 or displayed on the display screen of the data collection device 4.
　次に、ステップＳ１１１にて、第１の収集処理部４００は、物理量計測装置３との通信を終了するための通信終了要求を物理量計測装置３に送信する。そして、ステップＳ１２０にて、第１の収集処理部４００は、第１の監視周期Ｓ１による監視時点が到来したか否かを監視し、次の監視時点が到来したと判断した場合には、上記のステップＳ１００に戻る。 Next, in step S111, the first collection processing unit 400 transmits a communication termination request to the physical quantity measuring device 3 to terminate communication with the physical quantity measuring device 3. Then, in step S120, the first collection processing unit 400 monitors whether or not the monitoring time point according to the first monitoring cycle S1 has arrived, and if it is determined that the next monitoring time point has arrived, the first collection processing unit 400 The process returns to step S100.
　一方、ステップＳ２４０にて、演算処理部３２０は、データ収集装置４から通信終了要求を受信すると、データ収集装置４との間で通信を終了する。次に、ステップＳ２５０にて、演算処理部３２０は、データ収集装置４から通信終了要求を受信したか否かに応じて終了条件が満たされたか否かを判断するが、通信終了要求を受信したため、ステップＳ２５１にて、終了条件が満たされたと判断する。そして、ステップＳ２５２にて、演算処理部３２０は、スリープ状態に移行し、新たな通信開始要求を受信するまでスリープ状態を維持する。 On the other hand, in step S240, upon receiving the communication termination request from the data collection device 4, the arithmetic processing unit 320 ends communication with the data collection device 4. Next, in step S250, the arithmetic processing unit 320 determines whether the termination condition is satisfied depending on whether or not a communication termination request is received from the data collection device 4. , in step S251, it is determined that the termination condition is satisfied. Then, in step S252, the arithmetic processing unit 320 enters a sleep state and maintains the sleep state until a new communication start request is received.
　以上のようにして、演算処理部３２０は、通信開始要求を受信する毎にスリープ状態から復帰して第１の処理データＲｐ１を生成する第１の演算処理を実行し、通信処理部３２１により第１の処理データＲｐ１を繰り返し送信する。一方、第１の収集処理部４００は、第１の監視処理により第１の監視周期Ｓ１が経過する毎に通信開始要求を繰り返し送信することにより、処理データＲｐ１を収集する。なお、ステップＳ２００～Ｓ２２１、ステップＳ２４０～Ｓ２５２が演算処理工程、ステップＳ２３０が通信処理工程に相当する。 As described above, each time the arithmetic processing unit 320 receives a communication start request, it returns from the sleep state and executes the first arithmetic processing to generate the first processing data Rp1. 1 processing data Rp1 is repeatedly transmitted. On the other hand, the first collection processing unit 400 collects processing data Rp1 by repeatedly transmitting a communication start request every time the first monitoring cycle S1 elapses through the first monitoring process. Note that steps S200 to S221 and steps S240 to S252 correspond to arithmetic processing steps, and step S230 corresponds to a communication processing step.
（第２の監視動作）
　以下では、データ収集装置４が、第２の監視動作を開始するように指示する入力操作を受け付けた場合について、図６及び図７を参照して説明する。なお、図６及び図７に示す各ステップにおいて、図５と同様の処理を行うステップに対して図５と同一のステップ番号を付与している。 (Second monitoring operation)
Below, a case where the data collection device 4 receives an input operation instructing to start the second monitoring operation will be described with reference to FIGS. 6 and 7. Note that in each step shown in FIGS. 6 and 7, the same step numbers as in FIG. 5 are assigned to steps that perform the same processing as in FIG.
　まず、データ収集装置４の第２の収集処理部４０１は、上記の入力操作を受け付けると、図６に示すステップＳ１００にて、物理量計測装置３との通信を開始するための通信開始要求を物理量計測装置３に送信する。 First, when the second collection processing unit 401 of the data collection device 4 receives the above input operation, in step S100 shown in FIG. Send to measuring device 3.
　そして、ステップＳ２００にて、物理量計測装置３の演算処理部３２０は、データ収集装置４から通信開始要求を受信すると、データ収集装置４との間で通信を開始し、ステップＳ２１０にて、開始条件が満たされたと判断する。その際、制御部３２がスリープ状態である場合には、ステップＳ２１１にて、スリープ状態から復帰する。 Then, in step S200, when the arithmetic processing unit 320 of the physical quantity measuring device 3 receives the communication start request from the data collecting device 4, it starts communication with the data collecting device 4, and in step S210, the processing unit 320 of the physical quantity measuring device 3 is determined to be satisfied. At this time, if the control unit 32 is in the sleep state, it returns from the sleep state in step S211.
　次に、ステップＳ２２０にて、演算処理部３２０は、物理量データＤを所定のデータ点数Ｄｎ（本実施形態では、Ｄｎ＝「４点」）だけ繰り返し取得し、ステップＳ２２１にて、その取得した４点分の物理量データＤ１に対して演算を行うことにより第１の処理データＲｐ１を生成する。そして、ステップＳ２３０にて、通信処理部３２１は、ステップＳ２２０～Ｓ２２１（第１の演算処理）で生成した第１の処理データＲｐ１をデータ収集装置４に送信する。 Next, in step S220, the arithmetic processing unit 320 repeatedly acquires the physical quantity data D by a predetermined number of data points Dn (in this embodiment, Dn = "4 points"), and in step S221, the The first processing data Rp1 is generated by performing calculations on the physical quantity data D1 for the points. Then, in step S230, the communication processing unit 321 transmits the first processing data Rp1 generated in steps S220 to S221 (first calculation processing) to the data collection device 4.
　そして、ステップＳ１１０にて、第２の収集処理部４０１は、データ収集装置４から第１の処理データＲｐ１を受信すると、その第１の処理データＲｐ１を出力する出力処理を行う。ここで、図６の破線で示すステップＳ１１１、Ｓ２４０は、実際には実行されない処理であり、第２の収集処理部４０１は、第１の処理データＲｐ１の出力処理を行った後に、通信終了要求を物理量計測装置３に送信しない。 Then, in step S110, when the second collection processing unit 401 receives the first processed data Rp1 from the data collection device 4, it performs an output process to output the first processed data Rp1. Here, steps S111 and S240 indicated by broken lines in FIG. 6 are processes that are not actually executed, and the second collection processing unit 401 outputs the communication termination request after outputting the first processing data is not transmitted to the physical quantity measuring device 3.
　そのため、ステップＳ２５０にて、演算処理部３２０は、データ収集装置４から通信終了要求を受信したか否かに応じて終了条件が満たされたか否かを判断するが、通信終了要求を受信しないため、終了条件が満たされていないと判断し、ステップＳ２６０に進む。 Therefore, in step S250, the arithmetic processing unit 320 determines whether the termination condition is satisfied depending on whether or not a communication termination request is received from the data collection device 4, but since the communication termination request is not received. , it is determined that the termination condition is not satisfied, and the process proceeds to step S260.
　そして、ステップＳ２６０～Ｓ２６２にて、演算処理部３２０は、第２の演算処理を実行する。具体的には、演算処理部３２０は、ステップＳ２６０にて、所定の待機時間Ｗｔだけ待機状態に移行する。そして、その待機時間Ｗｔの経過後に、ステップＳ２６１にて、最新時点の物理量データＤｎｅｗを取得し、ステップＳ２６２にて、その取得した最新時点の１点の物理量データＤｎｅｗと、最新時点よりも過去に取得した過去時点の３点の物理量データＤｐｓａｓ（Ｄｐｓａｓ１、Ｄｐｓａｓ２、Ｄｐｓａｓ３）とからなる４点分の物理量データＤ２（Ｄｎｅｗ、Ｄｐｓａｓ１、Ｄｐｓａｓ２、Ｄｐｓａｓ３）に対して演算を行うことにより第２の処理データＲｐ２を生成する。なお、過去時点の物理量データＤｐｓａｓは、３回分前までに取得した物理量データＤであり、記憶部３４から読み出される。そして、最新時点の物理量データＤｎｅｗは、記憶部３４に記憶されて、次回の第２の演算処理では、過去時点の物理量データＤｐｓａｓとして読み出される。 Then, in steps S260 to S262, the arithmetic processing unit 320 executes the second arithmetic processing. Specifically, the arithmetic processing unit 320 transitions to a standby state for a predetermined standby time Wt in step S260. Then, after the waiting time Wt has elapsed, in step S261, the physical quantity data Dnew at the latest point in time is acquired, and in step S262, the physical quantity data Dnew at one point at the acquired latest point in time is combined with the physical quantity data Dnew at the latest point in time. The second processed data is obtained by performing an operation on the four points of physical quantity data D2 (Dnew, Dpsas1, Dpsas2, Dpsas3), which is made up of the acquired three points of physical quantity data Dpsas (Dpsas1, Dpsas2, Dpsas3) at the past point in time. Generate Rp2. Note that the physical quantity data Dpsas at the past point in time is the physical quantity data D acquired up to three times before, and is read out from the storage unit 34. Then, the physical quantity data Dnew at the latest point in time is stored in the storage unit 34, and in the next second calculation process, it is read out as the physical quantity data Dpsas at the past point in time.
　次に、ステップＳ２７０にて、通信処理部３２１は、ステップＳ２６０～Ｓ２６２（第２の演算処理）で生成した第２の処理データＲｐ２をデータ収集装置４に送信する。 Next, in step S270, the communication processing unit 321 transmits the second processed data Rp2 generated in steps S260 to S262 (second calculation processing) to the data collection device 4.
　そして、ステップＳ１３０にて、第２の収集処理部４０１は、データ収集装置４から第２の処理データＲｐ２を受信すると、その第２の処理データＲｐ２を出力する出力処理を行う。 Then, in step S130, when the second collection processing unit 401 receives the second processed data Rp2 from the data collection device 4, it performs an output process to output the second processed data Rp2.
　一方、ステップＳ２９０にて、演算処理部３２０は、データ収集装置４から通信終了要求を受信したか否かに応じて終了条件が満たされたか否かを監視する。 On the other hand, in step S290, the arithmetic processing unit 320 monitors whether the termination condition is satisfied depending on whether a communication termination request is received from the data collection device 4.
　ここで、図７の破線で示すステップＳ１３１、Ｓ２８０が実行されない場合について説明すると、ステップＳ２９０にて、演算処理部３２０は、通信終了要求を受信しないため、終了条件が満たされていないと判断し、ステップＳ２６０に戻る。そして、ステップＳ２６０～Ｓ２６２（第２の演算処理）を実行し、ステップＳ２７０にて、第２の処理データＲｐ２をデータ収集装置４に送信する処理を終了条件が満たされるまで繰り返し実行する。そのため、ステップＳ１３０にて、第２の収集処理部４０１は、データ収集装置４から第２の処理データＲｐ２を繰り返し受信する。 Here, to explain the case where steps S131 and S280 indicated by the broken line in FIG. 7 are not executed, in step S290, the arithmetic processing unit 320 determines that the termination condition is not satisfied because the communication termination request is not received. , the process returns to step S260. Then, steps S260 to S262 (second arithmetic processing) are executed, and in step S270, the process of transmitting the second processed data Rp2 to the data collection device 4 is repeatedly executed until the termination condition is satisfied. Therefore, in step S130, the second collection processing unit 401 repeatedly receives the second processed data Rp2 from the data collection device 4.
　一方、図７の破線で示すステップＳ１３１、Ｓ２８０が実行される場合について説明すると、ステップＳ１３１にて、第２の収集処理部４０１は、通信終了要求を物理量計測装置３に送信する。ここで、第２の収集処理部４０１は、例えば、第２の監視動作を終了するように指示する入力操作を受け付けたり、第２の監視動作による監視期間が終了したりした場合には、通信終了要求を物理量計測装置３に送信するようにすればよい。 On the other hand, to explain the case where steps S131 and S280 indicated by the broken line in FIG. 7 are executed, in step S131, the second collection processing unit 401 transmits a communication termination request to the physical quantity measuring device 3. Here, the second collection processing unit 401 receives an input operation instructing to end the second monitoring operation, or when the monitoring period of the second monitoring operation ends, the second collection processing unit 401 receives a communication A termination request may be sent to the physical quantity measuring device 3.
　そして、ステップＳ２８０にて、演算処理部３２０は、データ収集装置４から通信終了要求を受信すると、データ収集装置４との間で通信を終了し、ステップＳ２９０にて、データ収集装置４から通信終了要求を受信したか否かに応じて終了条件が満たされたか否かを判断するが、通信終了要求を受信したため、ステップＳ２５１にて、終了条件が満たされたと判断する。そして、ステップＳ２５２にて、演算処理部３２０は、スリープ状態に移行する。 Then, in step S280, upon receiving the communication termination request from the data collection device 4, the arithmetic processing unit 320 terminates the communication with the data collection device 4, and in step S290, the arithmetic processing unit 320 terminates the communication from the data collection device 4. It is determined whether the termination condition is satisfied depending on whether a request is received or not. Since a communication termination request has been received, it is determined in step S251 that the termination condition is satisfied. Then, in step S252, the arithmetic processing unit 320 shifts to a sleep state.
　以上のようにして、演算処理部３２０は、第１の処理データＲｐ１を生成する第１の演算処理を実行した後、第２の監視周期Ｓ２に対応する待機時間Ｗｔによる待機状態に移行し、第２の処理データＲｐ２を生成する第２の演算処理を繰り返し実行することにより、通信処理部３２１により第２の処理データＲｐ２を繰り返し送信する。一方、第２の収集処理部４０１は、物理量計測装置３から第１の処理データＲｐ１を受信するとともに、第２の処理データＲｐ２を第２の監視周期Ｓ２に従って繰り返し受信する第２の監視処理を実行することにより、第２の監視周期Ｓ２が経過する毎に処理データＲｐ１、Ｒｐ２を収集する。なお、ステップＳ２００～Ｓ２２１、ステップＳ２４０～Ｓ２６２、Ｓ２８０～Ｓ２９０が演算処理工程、ステップＳ２３０、Ｓ２７０が通信処理工程に相当する。 As described above, after executing the first arithmetic processing to generate the first processing data Rp1, the arithmetic processing unit 320 shifts to a standby state according to the standby time Wt corresponding to the second monitoring cycle S2, The communication processing unit 321 repeatedly transmits the second processing data Rp2 by repeatedly executing the second arithmetic processing that generates the second processing data Rp2. On the other hand, the second collection processing unit 401 receives the first processing data Rp1 from the physical quantity measuring device 3 and performs a second monitoring process of repeatedly receiving the second processing data Rp2 according to the second monitoring cycle S2. By executing this, the processing data Rp1 and Rp2 are collected every time the second monitoring period S2 elapses. Note that steps S200 to S221, steps S240 to S262, and S280 to S290 correspond to arithmetic processing steps, and steps S230 and S270 correspond to communication processing steps.
　本発明に係る物理量計測装置３（データ処理装置３１）によれば、所定の開始条件が満たされると、演算処理部３２０が、データ点数分の物理量データＤ１に対して演算を行うことにより第１の処理データＲｐ１を生成する第１の演算処理を実行し、通信処理部３２１によりその第１の処理データＲｐ１を送信する。このとき、所定の終了条件が満たされることで、第２の演算処理は実行されない。これにより、１回分の処理データＲｐ１だけが送信されるので、例えば、傾向監視（第１の監視処理）に利用することができる。また、第１の監視処理では、待機時間Ｗｔによる待機状態に移行しないため、待機時間分の消費電力の低減が図られる。一方、第１の演算処理の実行後に所定の終了条件が満たされていないと、演算処理部３２０が、所定の待機時間Ｗｔだけ待機状態に移行し、最新時点の物理量データＤｎｅｗを含むデータ点数分の物理量データＤ２に対して演算を行うことにより第２の処理データＲｐ２を生成する第２の演算処理を、終了条件が満たされるまで繰り返し実行し、通信処理部３２１によりその第２の処理データＲｐ２を順次送信する。これにより、処理データＲｐ２が繰り返し送信されるので、例えば、リアルタイム監視（第２の監視処理）に利用することができる。その際、通常の動作状態よりも消費電力が少ない待機状態に待機時間Ｗｔだけ移行し、待機時間Ｗｔの経過に合わせて物理量データＤが取得されて演算が行われるので、無用な物理量データＤの取得や演算が回避されることによる消費電力の低減と、待機状態への移行による消費電力の低減とが図られる。したがって、監視周期が異なる第１の監視処理及び第２の監視処理を実現しつつ、消費電力の低減を図ることができる。 In the physical quantity measuring device 3 (data processing device 31) of the present invention, when a predetermined start condition is satisfied, the calculation processing unit 320 executes a first calculation process that generates first processed data Rp1 by performing calculations on the physical quantity data D1 for the number of data points, and transmits the first processed data Rp1 by the communication processing unit 321. At this time, a predetermined end condition is satisfied, so that the second calculation process is not executed. As a result, only one batch of processed data Rp1 is transmitted, which can be used, for example, for trend monitoring (first monitoring process). Furthermore, in the first monitoring process, the device does not enter a standby state due to the standby time Wt, so power consumption for the standby time is reduced. On the other hand, if the predetermined end condition is not satisfied after the execution of the first calculation process, the calculation processing unit 320 transitions to a standby state for a predetermined standby time Wt, and repeatedly executes the second calculation process in which the second processing data Rp2 is generated by performing calculations on the physical quantity data D2 for the number of data points including the latest physical quantity data Dnew until the end condition is satisfied, and the communication processing unit 321 sequentially transmits the second processing data Rp2. As a result, the processing data Rp2 is repeatedly transmitted, so that it can be used for real-time monitoring (second monitoring process), for example. At that time, the system transitions to a standby state that consumes less power than the normal operating state for the standby time Wt, and the physical quantity data D is acquired and calculated as the standby time Wt elapses, so that the acquisition and calculation of unnecessary physical quantity data D is avoided, thereby reducing power consumption, and the transition to the standby state reduces power consumption. Therefore, it is possible to reduce power consumption while realizing the first monitoring process and the second monitoring process with different monitoring periods.
